Problem with WLAN after deinstalling

[kaljak]

Hello,

I installed VirtualBox yesterday on my notebook with Windows 7,
then my host system didn't recognize any wireless signals anymore,
deinstalling Virtualbox also didn't help.

Can anybody of you point me in the right direction to handle that problem?

Thanks in advance!

try disabling the Host-Only interface into your network connections, see if it makes any difference
